Licensing For SQL Cluster

Hi,
I would like to setup a SQL server failover Cluster as described as URL below.
http://msdn.microsoft.com/en-us/library/hh231721.aspx
Understand that there will be 2 servers and shared storage are required.My question is do I need to 2 SQL Server license with CALs or just 1 SQL server license and CALs is enough for my condition? Because I heard that if the SQL is setting up as failover
cluster for any kind of SQL Server database work,there's no need to license the redundant hardware,So would like to confirm for it.
Thank you and looking forward for reply. ^^

Virtual environment license for sql and other dependencies of sharepoint in Azure

We have Microsoft ActionPack. And we use Sharepoit 2013 from ActionPack , which is installed on our server.
But our on premise server doesn't satisfy the hardware requirement for sharepoint, and thus it is too slow to use.
So we decided to move sharepoint 2013 to Microsoft azure.
But we don't have any idea of virtual environment license for sql and other dependencies of sharepoint in Azure.
Do we have to purchase separate license for sql server and other dependencies.?

Hi BabeeshC,
Before you deploy SharePoint 2013 on the Azure platform, you must ensure that your Azure virtualization solution meets all the licensing requirements.
Every element of a SharePoint 2013 farm that is installed on Azure virtual machines must comply with the licensing requirements for SharePoint 2013 and related and supporting technologies.
SharePoint 2010 and SQL Server licenses should be purchased separately.

Cannot enable SSRT for SQL cluster

Hi Everyone
I'm running DPM 2012 SP1 (Not R2). I've having trouble enabling the self service recovery tool for a SQL cluster.
I can get to the next step when I add a different standalone SQL server, however anything to do with a cluster will not work.
I've been following this link:
http://technet.microsoft.com/en-us/library/jj674322.aspx
Any ideas?

Hi,
try this..
The SQL server instance field expects the following format for a clustered instance.
<Cluster network name>\<SQL virtual name>\<instance name>
The database name field may contain a valid database for that instance or be left blank for all databases in that instance.
To determine the component names for the wizard is to gather the information
from the DPM console. The DPM GUI shows the following for a protected cluster
instance.
Cluster Network Name: SQL Server (INSTANCE1).sqlserver.fourthcoffee.com
sqlv1n1\instance1\master
sqlv1n1\instance1\model
sqlv1n1\instance1\msdb
sqlv1n1\instance1\foo
To configure these databases in the SSRT configuration tool the following would be entered for the
SQL server instance name.
"SQL Server (INSTANCE1).sqlserver.fourthcoffee.com\sqlv1n1\instance1"

Licensing for NT Cluster Server

I need to know what the licensing method is for a NT Cluster Server? One server is connected to the database and the other is in hot standby. Only the active server can connect to the database, unless it goes down, then the standby server will take over and connect. I would like to use Oracle standard edition, because the active server has only 4 processors. The standby server has 2 processors. There seems to be some confusion as to the number of processors for this system. Some in our group say that the total number of processors is 6, thus we must use Oracle Enterprise Edition. I say we have two separate computers, one with 4 processors one with 2 processors, and we need Oracle Standard Edition for both computers. Can anyone help me settle this arguement, with documentation?

Thanks for the responses.
The most I've been able to find out is that there is no licensing charge for the NW J2EE AS if you use it to support Bobj.
Not sure though if the same applies for an application other than Bobj.

Peter

Additional Node License for existing cluster

Hi,
I am having two MCS servers having call manager version 8.5 installed in a single cluster. Now I have bought one new MCS server with the same version call manager and I want to add this node in the same cluster but I am having only two node license installed in my call manager cluster and that is already being used.
Please help me how can I can get the license to add this additional node in the cluster. If I have to order something then please share the part code which I have to order.
Thanks,
Shaheen Sidana

Nodes are free with version 8.5, however you need to order the free part number and receive a PAK, contact your Cisco reseller to submit the order or you can try sending and email to [email protected] to see if they can assist.

SQL Server Licensing For EPM

If using SQL Server as your relational database to support your Oracle EPM environment and SQL Server is not licensed "Per-Processor". Do each of your Planning\Essbase users need a SQL Server CAL or do you just need one for the account being used to access the repository?

Based on my understanding (and you should speak with Microsoft directly) is anyone that is an end user of the solution needs to have a CAL and/or SQL needs to be CPU licensed. This is also how Oracle treats Essbase with third party software which may only use one batch user id -- you wouldn't be able to license one Essbase user and then have 3000 users coming off of a third party solution.
At the end of the day the CPU licensing for SQL server will make the most sense unless you have a really really small environment.

SQL standard 2012 licenses for SCCM 2012 R2

Hi,
We are implementing SCCM R2 for customer, is the license for SQL standard 2012 included in price for SCCM licenses, we have around 5000 mahcines to be managed also a Secondary with express edition installed .
can secondary and primary have different version of SQL for replication ? or it should be same version?
is there a requirement for SQL standard like processor (How many number of processer can be used if this
license is free of cost for SCCM2012 (any limitations ) ) Is license cost calculated based on processor ?
also how many DB can be installed with standard on single instance ? can we use it for WSUS, MDT DB?
how will i get this SQL standard free version from Microsoft any download location.
Please advise.
Thanks
Shuaib

SQL Server Standard is included with all System Center products. As Tim said CPUs are irrelevant in this case.
You can use whatever versions of SQL you like as long as they are supported. However isn't it always best to standardise.
You can install as many databases as you like as long as they are System Center related - the ones you mentioned are OK.
The customer should download SQL from their Microsoft Volume Licensing Center. If they choose the SQL that is bundled with System Center it will be pre-populated with a license key.

Increase Performance and ROI for SQL Server Environments

The Buzz from Microsoft Ignite 2015
NetApp was in full force at the recent Microsoft Ignite show in Chicago, talking about solutions for hybrid cloud, and our proven solutions for Microsoft SQL Server and other Microsoft applications.
Hot topics at the NetApp booth included:
OnCommand® Shift. A revolutionary technology that lets you move virtual machines back and forth between VMware and Hyper-V environments in minutes.
Azure Site Recovery to NetApp Private Storage. Replicate on-premises SAN-based applications to NPS for disaster recovery in the Azure cloud.
These tools give you greater flexibility for managing and protecting important business applications.
Chris Lemmons
Director, EIS Technical Marketing, NetApp
If your organization runs databases such as Microsoft SQL Server and Oracle DB, you probably know that these vendors primarily license their products on a "per-core" basis. Microsoft recently switched to "per-core" rather than "per-socket" licensing for SQL Server 2012 and 2014. This change can have a big impact on the total cost of operating a database, especially as core counts on new servers continue to climb. It turns out that the right storage infrastructure can drive down database costs, increase productivity, and put your infrastructure back in balance.
In many customer environments, NetApp has noticed that server CPU utilization is low—often on the order of just 20%. This is usually the result of I/O bottlenecks. Server cores have to sit and wait for I/O from hard disk drives (HDDs). We've been closely studying the impact of all-flash storage on SQL Server environments that use HDD-based storage systems. NetApp® All Flash FAS platform delivers world-class performance for SQL Server plus the storage efficiency, application integration, nondisruptive operations, and data protection of clustered Data ONTAP®, making it ideal for SQL Server environments.
Tests show that All Flash FAS can drive up IOPS and database server CPU utilization by as much as 4x. And with a 95% reduction in latency, you can achieve this level of performance with half as many servers. This reduces the number of servers you need and the number of cores you have to license, driving down costs by 50% or more and paying back your investment in flash in as little as six months.
Figure 1) NetApp All Flash FAS increases CPU utilization on your SQL Server database servers, lowering costs.
Source: NetApp, 2015
Whether you're running one of the newer versions of SQL Server or facing an upgrade of an earlier version, you can't afford not to take a second look at your storage environment.
End of Support for Microsoft SQL Server 2005 is Rapidly Approaching
Microsoft has set the end of extended support for SQL Server 2005 for April 2016—less than a year away. With support for Microsoft Windows 2003 ending in July 2015, time may already be running short.
If you're running Windows Server 2003, new server hardware is almost certainly needed when you upgrade SQL Server. Evaluate your server and storage options now to get costs under control.
Test Methodology
To test the impact of flash on SQL Server performance, we replaced a legacy HDD-based storage system with an All Flash FAS AFF8080 EX. The legacy system was configured with almost 150 HDDs, a typical configuration for HDD storage supporting SQL Server. The AFF8080 EX used just 48 SSDs.
Table 1) Components used in testing.
Test Configuration Components

Storage controller
AFF8080 EX
Data ONTAP version
Clustered Data ONTAP® 8.3.1
Drive number and type

Source: NetApp, 2015
The test configuration consisted of 10 database servers connected through fibre channel to both the legacy storage system and the AFF8080 EX. Each of the 10 servers ran SQL Server 2014 Enterprise Edition.
The publicly available HammerDB workload generator was used to drive an OLTP-like workload simultaneously from each of the 10 database servers to storage. We first directed the workload to the legacy storage array to establish a baseline, increasing the load to the point where read latency consistently exceeded 20ms.
That workload was then directed at the AFF8080 EX. The change in storage resulted in an overall 20x reduction in read latency, a greater than 4x improvement in IOPS, and a greater than 4x improvement in database server CPU utilization.
Figure 2) NetApp All Flash FAS increases IOPS and server CPU utilization and lowers latency.
Source: NetApp, 2015
In other words, the database servers are able to process four times as many IOPS with dramatically lower latency. CPU utilization goes up accordingly because the servers are processing 4x the work per unit time.
The All Flash FAS system still had additional headroom under this load.
Calculating the Savings
Let's look at what this performance improvement means for the total cost of running SQL Server 2014 over a 3-year period. To do the analysis we used NetApp Realize, a storage modeling and financial analysis tool designed to help quantify the value of NetApp solutions and products. NetApp sales teams and partners use this tool to assist with return on investment (ROI) calculations.
The calculation includes the cost of the AFF8080 EX, eliminates the costs associated with the existing storage system, and cuts the total number of database servers from 10 to five. This reduces SQL Server licensing costs by 50%. The same workload was run with five servers and achieved the same results. ROI analysis is summarized in Table 2.

The takeaway here is that you can replace your existing storage with All Flash FAS and get a big performance bump while substantially reducing your costs, with the majority of the savings derived from the reduction in SQL Server licensing costs.
Replace your existing storage with All Flash FAS and get a big performance bump while substantially reducing your costs.
Maximum SQL Server 2014 Performance
In addition to the ROI analysis, we also measured the maximum performance of the AFF8080 EX with SQL Server 2014. A load-generation tool was used to simulate an industry-standard TPC-E OLTP workload against an SQL Server 2014 test configuration.
A two-node AFF8080 EX achieved a maximum throughput of 322K IOPS at just over 1ms latency. For all points other than the maximum load point, latency was consistently under 1ms and remained under 0.8ms up to 180K IOPS.
Data Reduction and Storage Efficiency
In addition to performance testing, we looked at the overall storage efficiency savings of our SQL Server database implementation. The degree of compression that can be achieved is dependent on the actual data that is written and stored in the database. For this environment, inline compression was effective. Deduplication, as is often the case in database environments, provided little additional storage savings and was not enabled.
For the test data used in the maximum performance test, we measured a compression ratio of 1.5:1. We also tested inline compression on a production SQL Server 2014 data set to further validate these results and saw a 1.8:1 compression ratio.
Space-efficient NetApp Snapshot® copies provide additional storage efficiency benefits for database environments. Unlike snapshot methods that use copy-on-write, there is no performance penalty; unlike full mirror copies, NetApp Snapshot copies use storage space sparingly. Snapshot copies only consume a small amount of storage space for metadata and additional incremental space is consumed as block-level changes occur. In a typical real-world SQL Server deployment on NetApp storage, database volume Snapshot copies are made every two hours.
First introduced more than 10 years ago, NetApp FlexClone® technology also plays an important role in SQL Server environments. Clones are fully writable, and, similar to Snapshot copies, only consume incremental storage capacity. With FlexClone, you can create as many copies of production data as you need for development and test, reporting, and so on. Cloning is a great way to support the development and test work needed when upgrading from an earlier version of SQL Server. You'll sometimes see these types of capabilities referred to as "copy data management."
A Better Way to Run Enterprise Applications
The performance benefits that all-flash storage can deliver for database environments are significant: more IOPS, lower latency, and an end to near-constant performance tuning.
If you think the performance acceleration that comes with all-flash storage is cost prohibitive, think again. All Flash FAS doesn't just deliver a performance boost, it changes the economics of your operations, paying for itself with thousands in savings on licensing and server costs. In terms of dollars per IOPS, All Flash FAS is extremely economical relative to HDD.
And, because All Flash FAS runs NetApp clustered Data ONTAP, it delivers the most complete environment to support SQL Server and all your enterprise applications with capabilities that include comprehensive storage efficiency, integrated data protection, and deep integration for your applications.
For complete details on this testing look for NetApp TR-4303, which will be available in a few weeks. Stay tuned to Tech OnTap for more information as NetApp continues to run benchmarks with important server workloads including Oracle DB and server virtualization.

SQL Cluster Management Pack

Hello,
I do not see a specific Management Pack for SQL Cluster... It seems to be the SQL Management Pack 6.1.400.0 and the Operating System Cluster Management Pack...6.0.6720.0 for Windows Server 2008 Cluster Management Library ...
Am I right?
Thanks,

I implemented the low-privilege setup from the SQL MP guide because on a few standalone SQL instances and one SQL 2012 cluster, not all scripts were running. The SQL cluster is a two node cluster with 2 SQL instances in and active/active config (One
instance is active on each node in the cluster). On the standalone SQL instances, the low-privilege setup is working great. On the SQL cluster it is not. Reading the latest SQL MP guide, it appears that SQL 2012 cluster are supported for
monitoring. I've made the additional configuration changes that the MP guide says is required for cluster monitoring. I am getting PowerShell script execution error messages in the OpsMgr console stating a lack of permissions. When I look
at the SQL error logs, I see that something is trying to log into the databases as NT AUTHORITY\SYSTEM and can't because access is denied. That login is not mapped to any databases - obviously. Why would these workflows be trying to execute as
NT AUTHORITY\SYSTEM and not one of the the action accounts in the SQL RunAs profiles that I've setup and deployed to the two cluster nodes?

Can we install PowerPivot for SharePoint on a SQL cluster?

We are going to deploy SharePoint 2013 with PowerPivot for SharePoint (installed from SQL Server media). According to what I've read out there for a small or medium farm, the recommendation is to install PowerPivot for SharePoint on
every SharePoint application server in the farm. However, accoding to the licensing doc I've pasted below, PowerPivot can be run outside the SharePoint farm. We are going with SQL Server 2012 Enterprise edition. PowerPivot requires a SQL
Server license for each server. To save money on licenisng, can we install PowerPivot for SharePoint on the 2 SQL Server cluster nodes (as a separate instance of course)?

http://vcollogan.knows.it http://twitter.com/orbhot

Hi Vincent,
PowerPivot for SharePoint is an Analysis Services instance in tabular mode. This
whitepaper mentions that clustering Analysis Services in SharePoint-integrated mode is not supported (page 8 under SSAS Server Modes.) You can, however, install it as a standalone
instance on the nodes of the cluster and let SharePoint handle the load balancing.
My apologies for the confusion on installing the SharePoint binaries on the PowerPivot instance. You don't need to install the SharePoint binaries if it is outside of the SharePoint farm. I was looking at my build documentation where I have both Reporting
Services and PowerPivot on the same machine with the same reason - reduce licensing cost - and similar to the 3-tier topology but with all of the service application and content databases on the database tier.

SQL Cluster requiremnt for Lync 2013

Hi
We are are planning to deploy Lync 2013 enterprise. Planning to use SQL cluster. Would like to clarify whether we must create a sepearte sql instance for Lync 2013 or can we use an existing shared instance to create a seperate database for Lync.
We prefer 2nd approach. Is there any issues or demerits using existing shared SQL instances?

This kind of question is very common. Basically here is the Microsoft Documentation about it.
Database software support in Lync Server 2013
https://technet.microsoft.com/en-us/library/gg398990.aspx
This point is the important: "If you collocate Lync Server databases with other databases, we highly recommend assessing all factors that might affect availability and performance, as well as ensuring that, if one node fails, the remaining node can
handle the load. To verify failover capabilities, we recommend testing all failover scenarios."
We can say the following: It's recommended to use a separate SQL server for Lync, however collating Lync database with other SQL databases will work, but has an high probability of present some performance problems. Many customers prefer to use this option
considering the cost of SQL licenses.
It is important to consider all the hardware requeriments for the Lync Server BackEnd role:
https://technet.microsoft.com/en-us/library/gg398835.aspx because the normal issue when customers share the SQL server with other instances is due to performance issues. Also note
that if you have multiple front end pools, these cannot share a SQL server.

SQL Licensing for Enterprise environment

Hi Guys,
currently we are planing our possible ways to migrate to Lync2013. Due to our Microsoft-EA we already own Lync Enterprise CALs and 3 Lync Server.
Now we have some reallly important questions on the Backend SQL issue:
after all we got confilicting statements from our MS-Licensing Partner an some Consultants.
1. ) it looks like, that Microsoft does not support an "activ/activ"-SQL Cluster even if LYNC gets an own instance.
this is an unbelievable statemen in consideration of the face a customer already spent a lot of bucks for the SQL-Core-LICs.
2.) if we'll use a dedicated SQL Standard Edition we also need SQL-CALs in addition to the Lync-CALs for all users using LYNC. the LYNC Enterprise-CAL does not contain the right to access the SQL-host. otherwise we need SQL-corelicenses which are ridiculous
expensive.
Is there someone who solved this issue for an supported environment.
regards
Heiko

Hi,
First let's clarify some points
1- There is no requirements for SQL CAL licensing For Lync, disregarding the SQL version that you are using ( standard/Enterprise), why ? because :
Lync Users doesn't directly access the SQL backend
and also these licences are already covered by the Lync Server License that you already purchased.
2- The only way to have an Active/Active SOL Cluster, is by configuring Always On availability Features and indeed Lync server 2013 doesn't support these features.
3- When it comes to SQL licensing options the only the SQL Standard edition has Sever/CAL or Per core Licensing option. Where the SQL Enterprise Edition can only be licensed with the Per-core option.
4- Lync Server 2013 support SQL Mirroring or SQL failover cluster as database high availability options. I both cases the following is applicable:
Only active SQL instances requires licenses
dedicated SQL instances can be hosted on Servers which are part of always on availability groups or Failover Cluster
